FEA BASED STATIC STRUCTURAL ANALYSIS OF UNCORRODED EXPANSION BELLOW BASED ON ASME AND RCB 8 CODE

Abstract

In process industries heat exchangers are the important element used. It deals with fluids having high temperature and pressure, which results in thermal stresses. So in order to absorb thermal expansion metal bellows are provided over the shell. Expansion Joints are provided on the shell side of heat exchanger. It allows the free expansion of shell relieving tubesheet & tube to tubesheet weld junction. Thus preventing its failure. In this paper the expansion bellow was analyzed for different loading conditions as per TEMA standards using Finite Element Analysis in ANSYS.
